To all whom 1'1 may (o/worn..- Be it known \lnn l, (lisonon E.

The subject of my present invcniion is n l improvement on iho oil-burner shown in n 3. former patent, No. r 741,867, October 20, i 1903. Y In addition to fulfilling all the objcois set. 1 forth in said former potent my present oilburner is so arranged as to operate SHUCf'SS- fully with a minimui'n oil-prcssurc, and, further, the sieain is so thoroughly intcrn inglod with the oil before they issue from the nozzle of the humor as to insure ogoinsi the carbonl izing and choking up of tho lJHl1l0l. i I have made provision whereby iho inlcrior of tho buincr can be ins'lan'i'cur ously cleaned without the detaching or mooring l of anyof its parts. i I have set forth fully hereinafter the dol tails of the construction and tho csscmiol l features thereof and illustraiod them in the accompanying drawings, in which-- igure 1 iso sideelevutionnndpartiol scctionof the complete burner. Fig. 2 is o side elevation of .iihe inner plug of the nozzle. Fig". 3 is. a tronsveiseseciion on the line as of Fig. 2. r Fig. 4 is a transverse section on the lineyofFigQ. 7

, Referring now to the above views by nul moral-fl and 2 represent the oil and sivu-m l pipes of the burner, respectively, ihc lullcr J encircling the former. The oil-pipc 1 is pro vidcd with a valve 3, while tho sloiin'r-pipo 2 l is connected to the Volvo 4, (ho unions 5 and J 6 being provided to focilitsuc making the dc I sired connections. The ll]l(1'lll(liz1l'0 globe i valve 7 is for tho purposc of introducing n. l head of steam to the oil-pipe 1 for purl poses of cleansing. The outer GXllI'Ollili) oithe pipe 2i s threaded to the head 8,thc onior extremity of which is formed with. the twin slots .9, from which the intermingled sticaln and oil issue. Within the hood 8 is the curved central deficcting-wrb 10, which no vents the heavy oil from falling to the hottom of the head and issuing from the lower slot, but causes ll io issue cvcnly lrom llUllI slo'is.

The outer oxlrcn ily ol ihc oil-pipv l is tluvudrd (o the nozzlc ll, ihc hollow mom of which enters the n cnzhcr 13, 'llH lui or living ilurodcd zrgzriusi n shouldvr in the hood 8.

Screwed inio ihc onto! cxlrcn ii v of 1 ho n'cmbvr 13 is the plus 15, the inner cxtron'iiy of which is conical and is adopted [0 deduct the oil and swam mid ihrow ii ilirough tho periormion lli whcrc il sllilu s against the inner wall of tho hood 8. The oil and steam are nextinterrupicd und caused to inivrniinglc by means of tho inimior flange 17, which is in line with the dcprossod (iicumfcimnizil groove in the plug 15.

The construction and arrangement of the several parts of my invention being thus made known, the operation of the some will, it is thought, be readily understood by following the solid and dotted arrows, which in clients the course of the oil and steam, re spectivcly.

The parts are so arranged us to be readilyconnccicd, as the adjustable stem 12 and union 18 ail'ord an: ilo muons for adjustment.

In order to further add to the thoroughness with whirh the steam and oil are inter mingled, l have formed the dio onol grooves 19 in the threaded flange 2(),wh1oh directs the steam to travel in a. spiral course! about tho member 13. i

The peculiar construction and romhinw tion of ports enables the burner to be run with a very low fire, and owing, to the nor rowness of the oil and strum conduits the burner operates with a steady Home without pulling or blowing.

In on oil-burner, the combination with concentric steam and oil pipes and a burnen head having discharge-apertures, of a memwithin the steam-passage and threaded flange at its intermediate ortion adapted to screw into on agement with the interior of the head, Sflit member extending front and rear of the flange and having a having a passage longitudinally through it a for the reception of the nozzle end of the oil pipe, and said front extension forming a chamber into which steam and oil are delivd of the front i front extension being: radially perforated to allow the.minledoil and steam to escape into the burnerear 3.
